i have a pu205 and love the plasma. thought i was having an issue with it because it wasn't cutting very good and the tig was exploding my tunstens. i put a dessicant dryer on it and all the cutting problems were solved, i don't have an argon bottle to see if the dry airlines fixed the tig problem but i have a sneaky suspicion that'll be fixed as well. my cuts aren't anywhere near as pretty as worntorn's but it gets the job done just fine
